Ulna

This was certainly the case with this examination, although the examination request asked for three views only two were taken. In addition to the two initial views taken, a post reduction view was necessary to ensure the trochlea was properly seated in the trochlear notch of the ulna. Even though three views were originally requested, the technologist did not want to distress the patient any more than was necessary, so the two views taken were an anteroposterior view and a lateral view. Of course, due to the patient’s affliction these views were not taken in the standard manner. For instance, the first image taken was the lateral, which was taken with the patient seated in a wheelchair and the IR placed carefully under patient’s forearm and elbow. Also, because of the patient’s limited mobility of the extremity further accommodations needed to be made. Specifically, a slight angle was placed on the tube to ensure the proper anatomy was demonstrated and to reduce the amount of distortion. In contrast, for the anteroposterior…

This injury occurs when the bones of the forearm (radius and ulna) get dislocated out of place. Where these three bones meet, it becomes dislocated or “out of joint”. Come causes of most elbow dislocations is caused from falls, mainly when the arm is extended completely. If a person is involved in any traumatic incidents, it can result in an dislocation, weather its a car crash or falling while skiing. Some symptoms and signs may include; server pain, swelling, and inability to bend the arm…

This type of fracture involves an isolated fracture of the junction of the mid to distal radius with associated dislocation of the distal radiolunar joint which is often difficult to recognize. When there is presentation of a radial only fracture the radioulnar joint should be examined carefully on the x-ray (Gaillard, F., radiopaedia.org). According to Putigna & Ursone (emedicine.com) a relatively uncommon injury accounting for fewer than 5% of all forearm fractures is the Monteggia fracture.…

have learnt from participating and competing in this sport. This skill requires many different muscles, bones, joints and their actions. Before I perform my skill I jump over the rope twice quickly and then slowly once. To jump over the rope, I use flexion to bend my elbow joint, moving my radius and ulna in a circular motion from my elbow joint and my shoulder joint uses circumduction to bring the rope over my head. My bicep brachii allows me to flex my elbow to perform this skill. I flex both…

Ulnocarpal Impaction Syndrome Ulnocarpal impaction syndrome is a condition in which tissue in the wrist (fibrocartilage) becomes damaged (impacted). This causes wrist pain on the side of the little finger (ulnar side). This often happens when one bone in the forearm (ulna) is longer than the other bone (radius). The ulna pushes against the wrist bones and pinches the fibrocartilage. If this condition is not treated, the fibrocartilage may eventually tear or wear away and become very painful. …

Consider the arm. The biceps and the triceps are on two sides of the upper arm bone (humerus) and attach to the fore arm bones (radius and ulna) from the inside and outside of the elbow joint. Contraction of the bicep causes your arm to fold. Contraction of the triceps causes your arm to extend , your biceps muscle is attached to your shoulder blade at one end and to your ulna in your forearm at the other end. When the biceps contracts, it shortens and pulls the ulna toward the shoulder blade…

(AnatomyExpert, 2014). 12. Abductor pollicis longus a. The abductor pollicis longus originates on the middle posterior surface of the ulna and radius, and inserts onto the proximal posteriolateral end of the 1st metacarpal bone (AnatomyExpert, 2014). b. Their main function is to abduct the thumb, but it also assists with the extension (AnatomyExpert, 2014). 13. Radial tunnel a. The radial tunnel is located on the posterior side of the forearm along the line of the…

in humans is to protect and house the brain. The cranium of the chicken is similar. However, the there are openings at the base of the cranium and these allow the brain and spinal cord to be directly connected. The maxilla forms the upper jaw in humans. It assists in the formation of certain cavities in the head along with fossae in chickens. In humans, the humerus serves as a insertion and origination point for numerous muscles, such as the pectoralis major and the deltoid. Its primary function…

CHIEF COMPLAINT: Left elbow pain. HISTORY OF PRESENT ILLNESS: Makayla is a very pleasant 4-year-old right-hand dominant female who presented to the emergency department yesterday after sustaining a fall while playing with another young family member. She fell onto an outstretched left arm and had pain in and around the left elbow. She was seen in the emergency department, where clinical and radiographic evaluations demonstrated the presences of a fracture through the left proximal ulna.…
